My father taught me this. Bottom the screws...gently...then turn them out 1 1/2 turns. That gives you a great starting point. And SAIT taught patience. Turn them little by little evenly. Each time you turn them in or out even 1/4 turn, rev the engine up a bit and wait for it to settle. Patience is the key as always John. Of course it IS better if you have a four gas analyzer, but the ear gets them pretty darn close! LOL

Wanna come out for play time Tom....sounds like you've mastered tuning a Quadrajet!! LOL!

Qjets, holley, AFB's all easy to tune. Make sure all vacum lines/ports are plugged or used.
1- make sure your timing is set correctly
2-set the base idle speed 750ish in neutral
3- #1 idle screw, turn it out or in until max rpm is gained, the turn back in till rpm drops 10-20rpm
4- reset idle speed 750 rpm
5- #2 idle screw same as #1
6- reset idle speed again to 750
7-done

The rpm speed at idle is for a stock to slightly cammed motor.
In gear it should beat about 600rpm.

Hope this helps bud if not come on out to Exshaw

Thanks! Once I put the rebuild kit in (early December) I set the base and have left it at that (had to do it by ear as the tach isn't working yet)....I got sidetracked on the front suspension and rebuild. Then I installed the headers and exhaust, as I wanted to set the carb once I had finished the exhaust and with the weather getting warm enough and streeets are clear enough I can maybe get a chance to play with the car a bit too.

Well folks, seems a motor might be coming my way. Ran into a fellow who has a 327 bored to 30 over with flat top pistons and Edelbrock aluminum heads (202-160???) I assume these numbers are for the chamber & intake runner but the Chamber seems extremely high????.

Apparently the motor runs and will obviously see this before any deal is to be made. My problem is that I have no idea what a 327 SB should go for in "decent" condition????

OK....back working on the car this weekend. The motor I was looking at fell through...:(

I have opened up the Rochester again to gain access to the idle mix screws (they were buried behind plugs). I set my timing to 4 degrees as per the tag, and then started setting my idle mix....it's pulling 18 inches of vacuum (not exactly sure on the RPM as the tach doesn't work) seems to run better but I still think it could be better.
